Wondering if anyone here has had a Genealogical DNA test for purposes of learning more about your distant (ie. not recent/paternity) ancestors. I have questions about the differences (price, service, thoroughness) of the various companies offering this service, the type of data that different tests can produce, and ways this data can be (constructively) interpreted.

I've finally decided to learn about how DNA (by reading Molecular Biology Made Fun And Simple), and I have a question about chromatin. The pictures you see of chromosomes are all taken when chromosomes have packed themselves into a visible structure to allow them to move around during Metaphase. If I have stranded, intact chromosomes in a test tube, can I force them to pack themselves into the Metaphase configuration? If so, how?

Are there any studies, past or present, devoted to the idea of deriving precise time of either conception or birth from DNA analysis? For conception, I can imagine a science fiction author describing a rhythmic pattern or pulse emitted by something in the DNA whose beats are somehow recorded somewhere, like the veritable second hand of a clock. For birth time I'm a little fuzzier on the possibilities, but one idea that occurred to me was the studying the effects of direct light (sun or artificial) on a baby's chromosomes when exposed for the first time (not counting any rays that might penetrate the womb through the mother). There is also the telomere clock to consider, about which I know very little.

I need solid scientific evidence that thought can change matter - how consciousness effects DNA structure, patterns and ultimately reality. Charts, studies, videos, all is welcome as a way of viewing and understanding how the mind's energy works in relation to physical matter. Thank you so much.

My GoogleFu has failed me. Does anyone know of a place I could send a swab of DNA from my cheek and get a photo of it back (after they do the Chomatography thing). Because I love these but I'm too cheap and figure given the source image I could do the rest myself.
